PATENT OFFICE.

JOHN" H. ANANSON, OF STIRLING, NEW JERSEY.

ATTACHMENT FOR TYPEWRITING MACHINES.

Application filed January-21, 1922. Serial No. 530,766.

To all whom it may concern Be it known that I. Jorm H. ANANSON, a citizen of the United States, and a resident of Stirling, county of Morris, and State of New Jersey, have invented certain new and useful"Improvements in Attachments for Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines and particularly to an attachment for such machines.

One of the objects of the invention is to provide simple, practical and effective means for simultaneously making a plurality of original typewritten copies.

Another object of the invention is to provide a device for making a plurality of typewritten copies adapted to be attached to any of the standard typewriting machines.

Another object of the invention is to provide an auxiliary ink ribbon attachment for typewriting machines whereby a pluralityof original typewritten copies may be made simultaneously and to provide means for guiding the additional sheets of paper to their proper positions with respect to the auxiliary or supplemental ribbons.

Further objects of the invention will appear from the following specification taken in connection with the drawings which form a art of this application and in which fig. 1 is a perspective view of a portion of a typewriting machine havin my auxiliary ribbon attachment mounted t ereon.

Fig. 2 is a perspective view of the paper guiding and auxiliary ink ribbon guiding plate or member.

Fig. 3 isa transverse sectional elevation taken through the paper feed roll and paper guiding members, and

Fig. 4 is a sectional elevation similar to Fig. 3 but.illustrating a plurality f auxiliary ink ribbon supporting and guiding members.

The invention, briefly described, comprises a member adapted to besupported on the feed carriage of a standard typewriter andhaving means for .supporting an auxiliary ink ribbon adjacent the usual ink ribbon and in proper operative position with respect to the type bars and further having means for guiding an additional sheet of paper to the proper position in the rear of the auxiliary ribbon.

Referring to the drawings, I have shown of standard make having the usual ink ribbon 11 mounted thereon and carried by spools 12 and 13 also supported on the' frame 10.

Upon the frame 10 is mounted the usual paper feed carriage upon which is supported the paper feed roll or platen 14, paper shelf or guiding member 15 and pressure rollers 16- for pressing the paper against the feed roll.

The ink ribbon 11 is guided through an intermediate vibrator 17 in front of the platen or feed roll and is adapted to be engaged by the selected type bar 18 in the usual manner. The ribbon 11 is fed from one spool to the other by any desired feedingmechanism as the carriage moves across the frame of the machine.

In order to obtain an additional original copy an auxiliary ink ribbon 20 is supported in the rear of the ink ribbon 11 and the auxiliary ribbon is mounted in slots 21 formed in lugs 22 secured to or formed integral with a thin paper and ribbon guiding plate or member 23. A longitudinal strip 24 is formed on or secured to the plate 23 along the front edge thereof and extends throughout the length of the plate to support the auxiliary ribbon 20 and prevent the sheet of paper in the rear thereof from engaging the ribbon. The plate 23 hasformed therein openings 25 to permit the passage ofthe pressure rolls 16 therethrough, thereby f insuring the proper feeding of the paper by in Figthe feed roll. From the showin 1, it. will be noted that the auxiliary ink ribbon 20 is supported slightly above the normal or inoperative position of the ink ribbon 20.

The auxiliary ribbon 20 is carried by spools 30 and 31 supported on brackets32 attached by screws or other suitable securing. means to the frame 10 of the machine. From the spools 30 and 31 the ribbon is guided through slots 33 in stationary guide arms 34 carried by the brackets 32. As clearly shown in Fig. 1 this method of guiding the ribbon 20 provides a sufiicient length of ribbon between the slots 33 and '21 in the late 23.

the brackets 34 to permit the usual reciprocation of the paper feed carriage and during each operation the straight portion of the ribbon 20 will Any suitable form'of drive for the auxiliary ribbon spools 30 and 31 may be provided and in the formof the invention illustrated the spools 12 and 13 have secured thereto 'or' to their spindles 12' and 13' sheaves or pulleys 35 and these pulleys are connected by belts 36 to corresponding pulleys 37 mounted on the auxiliary spools 30 and 31 or on the spindles 30' and 31' thereof.

operation may be briefly described as follows. The first sheet of paper or strip of paper is fed .into the machine and around .the feed roll 14 in the usual manner being guided by the shelf 15. In using the attach-.

ment, however, an'additional sheet will at the same time be inserted upon the plate 23 and will be simultaneously fed to a position I in the rear of the auxiliary inlr ribbon 20a The plate 23 therefore positively assures the proper positioning of the additional sheet ofperwith reference to the auxiliary ink rib In. If desired, the auxiliary ribbon 20 may be inked on only one side to prevent the copy from being printed on the back side of the front sheet of paper orin order to prevent this an additional sheet ,may be inserted in back of the front sheet.

It will be understood from the above specification that the device may be readily and quickly attached to any of the standard typewriting machines and 'it will also be evident that very few additional parts are necessary to obtain the desired results.

Although one specific embodiinent of the invention has been particularly shown and described, it will be understood that the inver'rtion is capable ofmodification and that pass through the slotsthereon, ribbon spools supported on said frame and having an ink ribbon thereon, a second set of ribbon spools on said frame operatively connected to said first named spools and having an auxiliary ink ribbon thereon, means for supporting said auxiliary ribbon in the rear of said first ribbon, and

means on said frame, disposed beyond the limits of travel of said carriage and in alinement with said auxiliary ribbon supporting means for supporting a length of auxiliary ribbon beyond the ends of the carriage.

2. In a typewriting machine 'having a frame, the combination with the paper feed carriage and usual feed roll, pressure rolls for pressing the paper .thereagainst, an ink ribbon, of a duplicate ribbon attachment comprising a curved paper guiding and auxiliary ribbon supporting plate adapted to be positioned against the feed roll, and means for guiding the auxiliary ribbon to positions substantially in alinement with the supporting plate, said means being supported from the machine frame and located beyond the limits of travel of the carriage.

3. In a typewriting machine having a frame, the combination with the paper feed carriage and usual feed roll, pressure rolls for pressing the paper thereagainst, and ink ribbon, of a duplicate ribbon attachment comprising a curved paper guiding and auxiliary ribbon supporting plate adapted to be positioned adjacent the feed roll, and

having openings to permit the pamage of I the pressure rolls, and means for guiding the, auxiliary ribbon to positions substantially in alinement with the supporting plate, said means being-supported from the machine frame and located beyond the limits I of travel of the carriage.

In witness whereof, I have hereunto set my hand this 19th day of January, 1922.

JOHN H. ANAN SON.
